I'll be honest, a lot of my hesitation around Hal Higdon is the daily time commitment. I sometimes find it hard to get out for my weekday runs at all, so doing just two of those and the long run has been manageable (though maybe having it be closer to a daily thing might help make it more routine). Walking for at least some of it makes it seem more doable; I can typically walk to/from work at least two days each week (1.2 miles each direction) and somehow that doesn't feel like such a commitment. I kind of like the idea of going time-based for the winter months, too. There's a half marathon in February I'm halfway considering, but I have a feeling that once it comes to that time of year I won't actually be excited to go out in the cold and run it, so I'm not currently planning my training around that.
I had gotten to week 13 of the Galloway beginners' marathon training plan from the runDisney website (
https://www.rundisney.com/running-training-programs/). Longest training run I did was 13 miles and it was challenging. Garmin says that one took me 4 hours and 11 minutes and I was doing two half hour runs during the week, so purely in terms of hours spent running the Higdon plan isn't more onerous--it's just talking myself into getting out there four or five days each week instead of three.
